Description

Предметом изобретени   вл етс  способ повышени  контрастности изображени  в ультразвуковом дефектоскопе , основанном на преооразовании возмун еиии ультраз1 уко1ЮГО пол  к видимое изобра кс 1;:е, за счет эффекта Реле .The subject of the invention is a method of enhancing the image contrast in an ultrasonic flaw detector based on the conversion of the disturbance and ultrasound field to the visible image x1; e, due to the Relay effect.

Описываемый способ заклю.аетс  в том, что среду с pc-reer-cKuмн частицами (суснсизис ;) иоменциот в электрическое no.ie, нанравленное параллельно нп11ра1 лснню ультразвука.The described method consists in the fact that the medium with pc-reer-cKumn particles (susnsis;) imenciot into an electrical no.ie, set parallel to np11ra1 ultrasonic ultrasound.

Релеевские частицы, выполнениые из материала пропод  цего элсктрически ток, стрем тс  ориентироватьс  в электрическом ruxie вдоль силовых линии, т. е. iicpnenдикул рпо расположению частичек и ультразпукоиом ноле.Rayleigh particles, made of a material pro- duced by an electric current, tend to orient themselves in an electrical ruxie along the lines of force, i.e., iicpneedicles of the location of the particles and the ultrasonic surface.

Частицы же на участка.х, где ультоатвуковое поле ослаблено, или полностью oTcyTCTisyeT (на.-п1чие -leibeKTa в ирозвучиваемом объекiv ) ориентируютс  электрическим иолем перпендикул рно к поверхиости ирозвучиваемого обч-.екта н 1К)г.10нипот надающпн на них ог ()С15етите,1Я ciiCT.ilpH concurrently; Ultrasonic and electric fields) plate particles, influenced by the ultrasonic field, are oriented parallel to the plane of the transducer and reflect niiiiiiii on nnkh light from the illuminator. Particles on the area x, where the ultrasonic field is weakened, or completely oTcyTCTisyeT (na.nu1-leibeKTa in a sounding object) are oriented electrically iol perpendicularly to the surface of the sounding obtch-ect. Take it, 1I ciiCT.

При этом получаетс  видимое изображение дефекта, контраст в котором соответстгл-ет контрасту между иочт ио.тныл отражением света и почти полным его ио -лон1еннем .This results in a visible image of the defect, in which the contrast corresponds to the contrast between the optical reflection of light and its almost full reflection.
